If a ground fault condition occurs, the keypads display
SERVC GND FAULT and the control panel transmits
a GROUND FAULT TROUBLE, AREA 1.
When the control panel recognizes that the ground
fault condition is corrected, and remains corrected for
between 5 to 45 consecutive sec, a Restoral Report is
sent.
The D9412GV3 and D7412GV3 Control
Panels log and print a Ground Fault event
as a Trouble Point 256 if communicating
in Modem IIIa
2
format. If communicating
in Contact ID format, the control panels
generate a Ground Fault (310) event.
4.5.3 Enabling Ground Fault Detection
To enable Ground Fault Detect Enable, lock (close)
the S4 Ground Fault Detect Pin on the control panel
(Figure 3).

4.5.5 Locking the Reset Pin
Locking the reset pin disables the control panel
(Figure 4). When the control panel is disabled, the
system ignores most keypad commands and points.
CALL FOR SERVICE appears in keypad displays
when the pin is locked down.
On-board relays (Terminals 6 and 7) and off-board
relays deactivate when the control panel is reset.
Terminal 8 has power when the relay is deactivated.
Activation interrupts power at that terminal. The on-
board relay (Terminal 8) remains deactivated when
the reset pin is locked in the disable position.
Releasing the reset pin from the closed position
resets the control panel. The control panel resets all
its timers, counters, indexes, and buffers. Any points
that restore after a reset do not generate Restoral
Reports.
If the reset pin is placed in the disable position when
all areas are armed, there must be an entry in the
Answer Armed program item. Refer to RPS
Parameters in the D9412GV3/D7412GV3 Program
Entry Guide (P/N: F01U170807).
Locking the pin in the disable position applies power
to the control panel and charges the battery while the
detection devices and keypads are installed.
